Hi All,
I've got a USB mem stick that seems to be dodgy, but I'm not sure.
I =know= it's not worth the time and effort financially, but I'd like to
be sure it's the stick, and not some other part of the system.
On this web page...
superuser.com/questions/376274/check-the-physical-health-of-a-usb-stick-in-linux
Someone suggested using this command...
sudo badblocks -w -s -o usbstick.log /dev/sdz
... where sdz is substituted for the actual device.
But, when I try the command with the stick unmounted, I get an error
message to this effect...
No such file or directory while trying to determine device size.
And, when I try the command with the stick mounted, I get an error
message to this effect...
/dev/sdb is apparently in use by the system. It is not safe to use
badblocks!
What's the obvious escape from this Catch-22 that I don't see?
Thanks.
Carl
Bayswater
